      Made of tremolite jade, the opaque artifact is grayish-white with multicolored stains (including tones of sauceyellow, grayblack, dark brown, and muted brown). Shaped like a trapezoidal axe with a slightly triangular top, both faces are decorated with symmetrical motifs. At the top, a shallow, basrelief continuous beastface pattern is incised using materialremoval and lineengraving techniques; beneath it, two parallel straightline patterns are carved, forming a distinct decorative unit. The upper body and both lateral edges are adorned with two sets of patterns—each formed by a pair of incised parallel lines creating a "冂"shaped design, within which five groups of symmetrical cloud motifs are further incised. Noticeable tool marks indicate the use of sharply edged instruments in the carving process. Although the jade originated from the western mountainous area of the Sichuan Basin and was produced locally, the beastface motif is typical of bronze vessels in central China during the Shang and Zhou dynasties. It holds significant historical, artistic, and scientific value for studying the jade processing techniques and the bronze civilization of the ancient Shu people in the Chengdu region during the Shang and Zhou dynasties.
